I think it was F9 for a boot menu, but if the HDD is failing you'll see a never ending repair loop. At the office we pull the HDD out and then try a boot from other media.
The issue of failing HDDs is pretty common so we are used to pulling out the drives to try to access in other PCs. Home users may be stuck with a shop counter.
I have an ASUS laptop Windows 8 and suddenly it will not boot. It is stuck in automatic repair mode.
Now in win 8 the f8 button does not work.i cant boot into safe mode. Also i tried to refresh by hitting f11 but f11 does nothing. I open bios and can not see boot options from usb...so i basically dont know what to do now..does anyone have hope?
